To @ZZ wiom it may Concern.' lle it lnowr. that li ROBERT B. Ron'mson, l :i citizen of the Uiiiiefi States, residing ai, Kans-n.5* City, in the County oi Jackson and Siate oi iliissouri, lnire'inventerl certain new and useful Iniprorenienis in leiziining Devices for D'enionn'alile Riina? oil which ilie following is zi Specification,

This invenion relates to imprmenients i retaining devices for izlie rlemonnleble rims i of wheels usingy pneiiiimtie tires, und it is my l object to proflnce zi simple (levire o' rois! allzu-actor which will enable :i rini to be quickly removed incl replaced and ieliiibl7 l Secured in position upon die wheel.

Specifically, the invention contemplates is. edging le vvice oi" 'which the liol member :intl niost oi lie porfis :ire reiiiiiiieel pernifi` nenly by lie folly of the wheel So that there l is no danger of :my of them beconiing lost or n'iisplzlcod in the proces@ oi'rohnngiing lie tires. v

2. In a device for securing demountable rims to Wheels, a Wedge member adapted to en age the rim and provided with a beveled ra ially extending portion having a pair of spaced bosses and a marginal bolt-engaging recess, and a spring-actuated bolt mounted the head is rotated, the continued rotation of the head causing it to be seated between said bosses with the wedge member held clamped against the rim.

In testimony whereof I afiX my signature in the presence of two witnesses.
